Be it known that: I, Josnrn; V ,DnsmAe RAIS, a citizen of the United States, and resident of New Bedford, l3ristol of Massachusetts, have invented certain new and useful Improvements in Attachments for Looms, of which the following is a speck themo'uth of the box fication.

This invention relates to looms and more particularly to an attachment objects of device which will prevent the loom operator from putting a shuttle in a box when no shuttle should be in the same; to provide such a device which is easily attachable to a loom, has very few parts and is efficient and dependable in action.

The single figure shows a perspective view of a portion of a loom with the attachment applied thereto.

One of the side frames 10 of the loom has mounted thereon as at 11 one of 12 of the lay 13. The lay may be of the usual construction having at one end a single shuttle box 14 and at the other end a plurality of shuttle boxes 15. At the rear of the loom a shaft 16 is rotatably mounted in the side frame and this shaft may have connections for operat'ng the picker sticks. Fixed to this shaft adjacent the side frame 10 is a cam 17 my attachment. This attachment includes a gate which is adapted to be moved to cover and uncover the mouth of the box 14. As clearly shown in the drawing, a lever 18 is pivotally mounted at 19 on the side frame 10 and carries a roller 20 which is adapted to cooperate with the periphery of the cam 17. A link 21 is pivotally connected at one end to the end 22 of the lever 18 and at its other end to the lower end of a vertically arranged rod 23. This rod is slidand guided by any suitable the bracket 24 and carries at its upper end a gate 25 which is adapted to cover the entrance to the box 14. ile I have shown this gate 25 as a plate, it is obvious that it may take any other suitable form.

In assembling the machine,the cam 17 is so positioned or attached to the shaft 16 that when a shuttle is not and should not be present in the box 14 the gate 25 will obstruct the mouth thereto. In the operation of the machine as the shaft 16 rotates means such as L s ecification of Letters Patent; i Application filed. October .24, 191

county, State therefor. The the invention are to provide a which is I adapted to operate Serial No. 127,459.

Y the pickercsticks are operated, the shut tle will be thrown from a box on one S1618 of the lay to a box on the other side ,By means, of the cam 17 thelever '18 will be OSOlllttGdon its pivotl9gand :thro'ugli the link 21 will reciprocate the rod 23 and also thegate 25 to alternately cover and uncover 14. As the timing'of the movements of these parts is such that the gate 25 is in front of thebox 14 when a shuttle should not be present therein it willbe obvious that if for any reason the loom is stopped an operator cann'otinsert a shuttle in the said box 14 when one'should not be present therein.

While I have mentioned the shaft 16 as being connected to operate the picker sticks, 1t ls'obvious that my attachment may be operated from any rotatable member of the V Patented Oct. 3o, 191 r 1. j

The only requirement is that the gate 25 be operated so that it will be open when a shuttle is properly in the box 14 and will be closed when a shuttle should not be present therein. -It is obvious that the details of the means for actuating the gate may be greatly varied without departing from thespirit of the invention.

Having thus described the invention what is claimed and desired to be secured by Letters Patent is:

1. In a loom'having a single box at one end of the lay, means for obstructing the, entrance to said box when a shuttle should be in a box at the other end of the lay to thereby prevent the operator from inserting a shuttle in said sing e box.

2. In a loom, a movable member arranged in front of the entrance to a box at one on of the lay, and means to automatically actuate said member to obstruct the said entrance when the box should be empty it away from said entrance when a shuttle should be in said box.

3. In a loom having a single box at one end of the lay, a gate movable into the path of the shuttle to and. from said box, andv means automatically operated by'the loom I for moving said gate to obstruct saidpath when the said boxshould be empty. Y

and to move 4. Ina loom having a single box at one no I timed relation cally operated. by the loom for gate away from said entrance tle should be in said box.

5. In a loom when a shutend of the lay, a movable gate arranged to said bo X When the Gonies of this patent may be obtained for moving. Sam

inglmeans for moving said gate away from said entrance when a shuttle should be in said box.

7; In a loom having a box at one end of end,a gate arranged to move across the mouth of said first mentioned box a member rotating in timed relation with the movement of the shuttle across thelay and means operated by said member to move said gate to obstruct the mouth of said box When no shuttle shonld be therein;
